How to choose your cockpit?
The stem connects the bar to the steerer: check the bar clamp diameter (the 31.8 mm standard, sometimes 35 mm) and the length, which affects your position (shorter = more agile). CNC aluminum combines light weight and stiffness. For MTB, a suspension fork is chosen by travel and technology: the air cartridge is light and adjustable, the coil simpler and sturdier. Check the compatible steerer diameter, axle and wheel size. Ergonomic grips round off comfort and grip.

Frequently asked questions
Which stem clamp diameter should I choose?
The current standard is 31.8 mm at the bar, with 35 mm on some MTBs and the older 25.4 mm. Check your bar's diameter to pick a compatible stem and a secure clamp.
Air or coil fork for MTB?
An air fork is light and finely adjustable to the rider's weight; a coil fork is simpler, sturdier and cheaper, but heavier. The choice depends on your budget and riding level.
How do I choose stem length?
A shorter stem makes steering sharper and the position more upright; a longer one stretches the position and adds stability at speed. Adjust it to your comfort, size and riding style.
